.tro v.A LLwnoM IT M A'r eoNoEnN: y n i Be it'hno'w'n that I, A. A, WILDER, of the city of Detroit, inthe county ofwayne, andState of Michigan, have invented a new and improved Machine for Planing and Otherwise Preparing Lumb'er'; and I do hereby declare that the following isla full and exact description of. the same,'rei`erence being had to the accompanying drawing, making a part of`this specication, and i'n which like parts are indicated bylilze letters in the several i figures.- v

The natureiof my invention consists 'in so constructing a planing machine, that .at 'the same time itwill -l tongue and groove, bead, rebate, and splitA lumber at one andthe same operation, making two pieces of dressed and finished Hooi-ing or ceiling out of one piece of-lumber without the uscof a saw.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction :Figure- 1 is a plan view of my machine. Figure 2, hn elevation of the same. Other parts represented will be mentioned hereafter.

@A represents the framework or support of my machine, not -di`erlng materially from any other planing machine. B is a drum or pulley, to which motion is communicated in anyidesirable manner, and around which pass severalbelts communicating motion to otherv parts. as mere motors. ais a belt, drivinga saw, C, which canbens'ed in my machine outside of its particular purpose to be hereafter described. At present we will suppose it not to be used. Belt b passing over drum B communicates motion to a pulley attached to a shaft, c, and on which there are other' pulleys, around which other belts pass.` .lhese belts are designated, by d and e,

and they drive the upper 'and lower groove-cutterscland di. fis a belt, passing over a pulley, f', ou the shaft of drum B, which operates certain parts in the front of the machine to be hereafter described, governing the feed-rollers infront, and by means of a lever, D, the feed-rolls or rollers can be operated-or not at pleasure. v

The beltfpasses over apulley,fl, on axis of whichis-a cog-wheehg, which gears into a larger one, g', which is on an arbor or shaft, L. Ou the opposite side from g', and on the same shaft, there is a cog-wheel, z', which gears into another cog-wheel, z", it gearing into another one, which is on a shaft, h. On' the shafts L and Il are `bevel-wheels E which gear ,int-o Ahorizontal bevelwheels E above, operatingthe luted feed-rollersvj.v Other bevel-wheels on the same shaft connect with horizontal ones which operate the secondaryfeed-ro1-lers r.

These duplicate sets of feedrollers are vmade adjustable above in any ordinary manner, as shown, and more especially below through the bevel-wheels E and E. The former sliding on its shaft h or L gives way to the pressure ou the luted rollers j through the bevel cog-wheels E on the lower extremity of their shafts. 4This adjustable arrangemcntgwhich is automatic, I consider of great importance. ll are adjustable guides, throngh `which passes4 the lumber to the feed-rollers jj andl.: le. v m is an, endless 'chain by whichv to regulate the cutting depth of the planing or rebating and togueing or beading cutter-head n. Between fthe feed-rollers and the cutter nis an adjustable roller, n,-made so hy.a set-screw, o, by which to press the boards against the fixed plate p, against which it bears when the cutter n operates on it. As the board passes along, and before reach-v ing the second tongueing-cutter nf', which-maltese. double tongue on tho opposite side like n dogs, it bearsl against another pressureplate,p, supporting it in this second operation; thisplate p being made adjustable by a l'set-screw, o. The board 'now being fed forward duringthc operation comes under an adjustableA frictionroller, q, connected `with a plate or shield, r, through which the arbor of the upper ciltter e passes,.this plate being attached -toliox of said arbor. The height of this upper cutter is regulated at pleasure by-meansof suitable gearing or adjustmentunnecessary to detail. These cutters make the grooves v and v', and the boardY emerging falls into two pieces or comes out two finished pieces without any previous searing.4 The cutters n and n can be so shaped as to not Aonly tongue each upper'and lower halfof the board fed in, but also bead the adjacent-parts as seen at wv.. The prcssure-rolle has 'a vertical movement alonggthe front extremity ofthe plate or shield r, and is pressed against the top edge of the board by means of a spring, 8, Sellcd t0 the top 0f said shield r. The tongueing-cntters t, secured to thecuttcr-hea-ds a and u, are adjustable vertically to suit the necessities of the case. These may be multiplied, and at their extreme outer edges small points round ofi` the tongues and nearly sever them, so that when the board which was fed in at one end comes out at thc other it will fall into tiro finishedv pieces of lumber. The bevel gear-wheels E and E which give motion to the iluted Feed-rollers j nre self-adjusting, hrwing a novel and useful construction, the outer rim of E taking into'a. groove on the under side of E; hence in whatever direction, in o1' out, the rollerj moves, and on the n xis ofwhich is fnstencrl E', it carries E with it., which slides on its shaft, yet revolving it by means of a key or fenthein4 Having thus described my invention. what I claim ns new, und desire to secure by Letters Patent of the United States, isri i 1. The combining :ind` arranging of cutters in n. planing machine, in the manner substnutially'ns shown und described, whereby lumber is prepared for oi'ing o1' ceiling by tongucing, grooving, :md 'planing the snine ot one operetion, nnd mnlging two or more finished pieces of lumber out of one without the use of n saw.

2. The self-adjusting feed bevcl-wheels E and E', when constructed :und operating in the .manner snbstnn tinlly :rs shown and described and for the purpose set forth.

3. The combination of the shield 1', spring s, and roller q, constructed and operated in the manner substantially as -shown and described and for.the purpose set forth.
